Ares SCR (Sport Configurable Rifle) is a semi-automatic rifle intended for civilian use – as a hunting, practice or home defense weapon. It is based on the extremely popular AR-15 rifle platform, but is configured to a more traditional look, which also conforms to stupid legal limitations, originally imposed by the now-defunct AWB’94 (Assault Weapons Ban, 1994-2004) and now carried forward by certain legislations in some of states within USA. Ares SCR rifle was originally developed in around 2003 by Geoffrey Herring, and was initially known as Herring MSR – Modular Sporting Rifle. After sunset of the AWB’94 this project was shelved for almost a decade, and finally went into production as Ares MCR in 2014.


Ares SCR rifles are available as complete rifles and carbines, as well as conversion kits that can use almost any existing AR-15 type upper receivers. Conversion kits include new lower receivers with stocks and return springs, as well as a new proprietary (and patented) bolt group.

The basic Ares SCR rifle is a gas-operated, semi-automatic weapon with Stoner-designed direct gas impingement system and rotary bolt locking. It uses aluminum alloy upper and lower receivers, connected by two captive cross pins. Bolt carrier of the SCR is noticeably shorter than any typical AR-15 bolt carrier, and features articulated “tail”, which connects to the return spring, located in the channel inside the shoulder stock. Lower receiver of the SCR rifle is designed to accept mil-spec AR-15 upper receivers and all Ar-15 type magazines. In basic configuration (with Ares-built upper receiver) there’s no bolt hold-open device (which is optional) and no dustcover on the ejection port. Trigger unit is also somewhat different from standard Ar-15, and it features cross-bolt manual safety located at the rear of the trigger guard.

Standard furniture includes polymer shoulder stock with semi-pistol grip (available in several configuration) and polymer forend. Ares-made SCR upper receivers feature “flat-top” configuration with no dust cover and no forward assist. However, shooters can use various compatible (“mil-spec”) upper receivers of their own choice to build different versions of the SCR.
